Light Discrimination Apparatus

The item I observed during class was the light
discrimination apparatus.This apparatus
demonstrates the various psychophysical methods used in visual discrimination.
The subject is supposed to watch the two 1.375” diameter light stimuli while
the examiner adjusts light intensity. The subject’s task is to determine when
lights are at an equal intensity or when one light is more or less bright than
the other. Each stimulus can be independently varied in intensity by the
subject or examiner. Light stimuli are presented using high intensity LED lights,
which are set up to give consistent and highly reliable intensity across its
usable range.

Perception

The psychology of Perception involves the interaction of our senses and our conscious mind. Perception is involved in every aspect of our lives as we make decisions and judgments based on what we experience. If you study diligently you will leave this course with a broad understanding of sensation and perception. From this general understanding you will be able to further investigate areas of interest by means of literature review and research on specific topics.
